LM2904YDT Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the LM2904YDT?
  The LM2904YDT can operate from -40°C to 125°C, making it suitable for a wide range of applications.
• How do I ensure the stability of the voltage regulator output?
  To ensure stability, it's essential to use a minimum output capacitance of 10uF, and a maximum ESR of 1.3 ohms. Additionally, the input capacitor should be at least 10uF with an ESR of 0.5 ohms or less.
• What is the minimum input voltage required for the LM2904YDT?
  The minimum input voltage required for the LM2904YDT is 7V, but it's recommended to use a minimum of 8V to ensure proper operation.
• Can I use the LM2904YDT in a high-current application?
  While the LM2904YDT can handle up to 1.5A of output current, it's not recommended for high-current applications. For high-current applications, consider using a more suitable voltage regulator, such as the L4940 or L4941.
• How do I protect the LM2904YDT from input voltage surges?
  To protect the LM2904YDT from input voltage surges, use a transient voltage suppressor (TVS) diode, such as the SMAJ58A, in parallel with the input capacitor.
